BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a computer casing, and in particular toa computer casing having an integral supporting frame.

2. Description of Prior Art

The conventional casing of a computer host includes a frame, a panel, arear plate and two side plates. The panel covers the front surface ofthe frame. The rear plate is connected to the back surface of the frame.The side plates are inserted to both sides of the frame. The frame isusually constituted by means of connecting a plurality of metallicsupports and a plurality of metallic plates. The connection can beachieved by screws or rivets.

However, in practice, such a structure still has drawbacks as follows.Since the frame is usually constituted by means of connecting aplurality of metallic supports and a plurality of metallic plates, theframe has so many constituent elements that increases the material costof the computer casing. Furthermore, the procedure for manufacturing andassembling the frame is complicated and time-consuming. As a result, themanufacture cost of the whole computer casing is increased. On the otherhand, since the metallic supports and the metallic plates are connectedby screws or rivets, the connecting portions may be loosened after along period time due to the vibration generated by the operation of theelements within the computer casing and the vibration generated by theoperation of a hard disk or fan. As a result, the structural strength ofthe computer casing will be reduced, which may cause some problems withregard to the usage of electronic devices in the computer casing.

Therefore, it is an important issue for the present Inventor to overcomethe above problems.

SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE INVENTION

The detailed description and technical contents of the present inventionwill be explained with reference to the accompanying drawings. However,the drawings are illustrative only but not used to limit the presentinvention.

Please refer to FIGS. 1 and 2. FIG. 1 is a perspective view showing theexternal appearance of the present invention, and FIG. 2 is aperspective view showing the external appearance of the supporting frameof the present invention. The present invention provides a computercasing, which includes a supporting frame 10, a rear plate 20 and twoside plates 30.

The supporting frame 10 comprises a top plate 11, a front plate 12 and abottom plate 13. The top plate 11 and the bottom plate 13 integrallyextend from the front plate 12. The top plate 11 is parallel to thebottom plate 13. The top plate 11 and the bottom plate 13 areperpendicular to the front plate 12 respectively. The supporting frame10 can be manufactured according to the following process. First,aluminum materials or other metallic materials can be extruded to form arectangular plate. Then, this rectangular plate is bent to form a Ushape, but the shape after bending is not limited thereto. Further, bothsides of the supporting frame 10 are formed with a reinforcing strip 14respectively. The reinforcing strip 14 penetrates the top plate 11, thefront plate 12 and the bottom plate 13, so that the thickness of bothsides of the supporting frame 10 becomes larger, thereby increasing thestructural strength of the supporting frame 10.

Furthermore, the top plate 11 is provided with a through trough 15. Bothends of the inner surface of the top plate 11 and the bottom plate 13are provided with a protruding rib 16 respectively. The protruding rib16 is provided with a plurality of penetrating holes 161 for allowingthe side plates 30 to be slidably inserted therein.

The top end and the bottom end of the rear plate 20 are connected to thetop plate 11 and the bottom plate 13 respectively. The side plates 30are connected to both sides of the supporting frame 10 respectively.

Please also refer to FIG. 3, which is a side view showing the supportingframe 10 of the present invention. The supporting frame 10 is integrallyformed by means of an extruding and bending process. The structuralstrength of the integrally-formed supporting frame 10 is superior tothat of the frame of a common computer casing. According to the presentinvention, using an extruding and bending process to manufacture thecomputer casing can save the working hours for manufacturing andassembling. Furthermore, in the computer casing of the presentinvention, the portions that are necessarily connected by fixingelements (not shown) are only the connecting portions between the topplate 11 and the rear plate 20 and those between the bottom plate 13 andthe rear plate 20, so that the number of the fixing elements can bereduced greatly. Therefore, the problem that a long-time operation ofthe devices within the computer casing may make the fixing elements toget loosened so as to reduce the structural strength of the computercasing can be prevented.

Please refer to FIG. 4, which is a perspective view showing the devicesarranged within the present invention. The devices that are arranged inthe computer casing comprise a main board 40, a power unit 50, a dataaccessing unit 60 and a connector module 70.

The main board 40 is connected to the supporting frame 10 and the rearplate 20. The main board 40 is arranged in one side of the supportingframe 10. The main board 40 is arranged to be much closer to one of theside plates 30. The power unit 50 is connected to the supporting frame10 and the rear plate 20. The data accessing unit 60 is connected to thesupporting frame 10.

Please refer to FIG. 5, which is a perspective showing the externalappearance of the supporting frame according to another embodiment ofthe present invention. In the present embodiment, the supporting frame10′ can have another form which is constituted of a front plate 12′ andtwo side plates 17 extending from both sides of the front plate 12′. Thesupporting frame 10′ also comprises a reinforcing strip 14′ penetratingthe two side plates 17 and the front plate 12′. The inner surface of theside plate 17 extends to have a plurality of protruding ribs 16′. Theprotruding ribs 16′ is provided with a plurality penetrating holes 161′.The supporting frame 10′ is combined with the corresponding top plate,the bottom plate and the rear plate (not shown) so as to constitute acomplete computer casing. In this way, the supporting frame 10′ also hasthe same advantages as the above-mentioned supporting frame 10 does.

More specifically, the supporting frame 10′ is manufactured in the samemanner as that of the supporting frame 10. That is, an aluminum materialis first extruded and bent to form a U-shaped supporting frame 10′. Theprotruding rib 16′ allows the top plate and the bottom plate (not shown)to be connected thereto. In the present embodiment, the top plate andthe bottom plate are parallel to each other, while the side plates 17are perpendicular to the front plate.

Therefore, the computer casing of the present invention has advantageousfeatures as follows.

(I) With the supporting frame 10 being integrally formed by an extrudingprocess, the manufacturing procedure can be simplified and themanufacture cost can be saved.

(II) With the supporting frame 10 being integrally formed, thestructural strength of the computer casing can be increased.

(III) With the supporting frame 10 being integrally formed, theinfluence on the elements and devices within the computer casing causedby external vibrations can be reduced, so that the elements and deviceswithin the computer casing can be protected from suffering damage.

According to the above, the computer casing of the present inventionalready has industrial applicability, novelty and inventive steps.Further, the structure of the present invention has not been seen inarticles of the same kind or let in public use. Therefore, the presentinvention conforms to the requirements for a utility model patent.
